The iSee (roflufocon D, roflufocon E) Daily Wear Orthokeratology Contact Lenses are indicated for daily wear in an orthokeratology fitting program for the temporary reduction of myopia of up to 5.00 diopters in non-diseased eyes. To maintain the orthokeratology effect of myopia reduction, lens wear must be continued on a prescribed wearing schedule.
Eyecare practitioners may prescribe the lenses for frequent/planned replacement wear, with cleaning, disinfection and scheduled replacement. When prescribed for frequent wear, the lens may be cleaned and disinfected using a chemical (not heat) lens care system.

The lenses are available in the following lens parameters: Base Curve, Center Thickness, Diameter, Spherical Power, Secondary Curves, Peripheral Curves, Multifocal Power.
The provided document is a 510(k) Premarket Notification for the iSee Daily Wear Orthokeratology Contact Lenses. It does not contain any information about acceptance criteria or a study proving the device meets acceptance criteria in the context of an AI/ML medical device.
Instead, the document focuses on demonstrating substantial equivalence to an already marketed predicate device (OPTIMUM GP OK Daily Wear Contact Lens). The basis for this equivalence is a comparison of technological characteristics, materials, production methods, and intended use.
Here's a breakdown of why this document doesn't provide the requested AI/ML device study information:
- Non-Clinical and Clinical Studies (Section VII): This section explicitly states:
- "The non-clinical performance data to establish the safety and effectiveness of contact lenses manufactured from roflufocon D and roflufocon E has been addressed by reference to the predicate devices."
- "Clinical performance data to demonstrate the safety and effectiveness of contact lenses manufactured from roflufocon D and roflufocon E have been addressed in previous applications."
This means that C&E GP Specialists, Inc. did not conduct new independent studies for this 510(k) submission. They are relying on existing data for the materials and the predicate device to establish safety and effectiveness.
Therefore, I cannot provide the requested information from this document for an AI/ML device since it is for a contact lens and references prior data rather than presenting a new study.

2. Sample Size for Test Set and Data Provenance
The provided document does not explicitly state a sample size for a "test set" in the context of clinical trials as it relies heavily on non-clinical testing and established clinical safety of the material and coating.
- Non-clinical Testing: Conducted "in vitro and in vivo" for toxicology and biocompatibility. All toxicology tests were conducted in accordance with GLP regulations.
- Wettability Data (Sessile Drop Contact Angle): The table indicates "n=30" for the average sessile drop contact angle measurements.
- Data Provenance: The document does not specify the country of origin for the non-clinical testing data. It also does not specify whether the data is retrospective or prospective, although GLP (Good Laboratory Practice) regulations generally imply prospective and controlled studies for toxicology.
3. Number of Experts Used to Establish Ground Truth and Qualifications
The concept of "experts" establishing ground truth as typically understood in AI/imaging studies (e.g., radiologists) is not applicable here. This submission focuses on the material's physical, chemical, and biological properties, and its substantial equivalence to predicate contact lenses. The "ground truth" for these tests is established by scientific methodologies and accepted standards (e.g., ISO for Dk, GLP for toxicology).
4. Adjudication Method for the Test Set
Adjudication methods (e.g., 2+1, 3+1) are not applicable here. These methods are typically used in clinical studies where human interpretation of medical images or patient outcomes requires consensus among multiple experts. The testing performed for this device involved laboratory measurements and analyses of material properties and biological responses, not subjective interpretations requiring adjudication.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
An MRMC comparative effectiveness study was not performed, nor is it applicable for this device. Such studies are typically conducted for AI-assisted diagnostic devices where the interaction between human readers (e.g., radiologists) and AI algorithms is being evaluated for improved diagnostic accuracy or efficiency. The HEXA100 contact lens is a passive medical device, not an AI diagnostic tool.
6. Standalone (Algorithm Only Without Human-in-the-Loop Performance) Study
A standalone algorithm-only performance study was not performed, nor is it applicable. This device is a contact lens, not an algorithm.
7. Type of Ground Truth Used
The "ground truth" for this submission is based on:
- Scientific and Engineering Standards: Measurements of physical properties (e.g., refractive index, specific gravity, oxygen permeability) and chemical properties.
- Biological Standards: Results from in vitro and in vivo biocompatibility and toxicology tests, often governed by ISO standards (e.g., ISO 10993 for biological evaluation of medical devices).
- Predicate Device Performance: The established safety and effectiveness profiles of legally marketed predicate devices serve as the benchmark for demonstrating substantial equivalence.
8. Sample Size for the Training Set
A "training set" is not applicable for this device. This is not a machine learning or AI device that requires a training set. The manufacturing process of contact lenses (lathe-cut, custom manufactured) and the material properties are characterized through traditional scientific and engineering methods.
9. How the Ground Truth for the Training Set Was Established
As there is no training set, this question is not applicable.
